ALBERT S. HOYT, OF CHICAGO, ILLINOIS.

SPECIFICATION forming part of Letters Patent No. 223,852, dated January 2"?, 1880.

Application led January 21, 1879.

To all whom 5t may concern:

Be it known that I, ALBERT S. Hov'r, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Grain-Binders; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specication.

In binding grain on a harvester, either by hand or automatically, a difficulty occurs in the separation of the grain for one sheaf from that which is to form the next.v The oblique manner in which the grain is delivered over the top of the elevator causes the straws to rinterlock and scat-ter badly while being bound and removed from the binders table. By my invention this is obviated, a separation to facilitate the labor of binding is formed, and a savi ing from loss bythe waste or scattering is effected.

`My invention consists in the construction and arrangement of the elevating and gavelforming mechanism of a harvester, and in the matter of effecting the separation of the grain for the different sheaves, as will be hereinafter more fully set forth.

In the drawings, Figure l is a side view. Fig. 2 is a back view. Fig. 3 is a front view, with horizontal apron in section. Fig. 4 is a sectional view on line x m of Fig. 2.

Q represents the frame. It has extension B, for supporting the cutting mechanism, and is composed of two horizontal beams, q, with other beams and braces, q to Q12, horizontal, oblique, upright, and cross.

A represents ahorizontal endless receivingapron ruiming upon the rollers a a, the journals of whichrevolve in bearings on the beams q. It is located behind the cutter-bar and receives the grain as it is cut thereby.

B represent-s an inclined endless elevatingapron running upon rollers b b, journaled in bearings on the oblique beams q.

C represents an elevating device, which is operated, in connection with the apron B, to

Y 5o elevate and deliver the grain to form the gavel.

It is composed of endless belts C C at each side, connected by cross-pieces C C', which are provided with suitable teeth or prongs. The belts C C run on enlargements of rollers C2 at the top and bottom. The lower roller, C2, is journaled in bars C3, which turn freely on the axle of the upper roller, C2, which is joined in bearings.

D represents a frame composed of wires d, which serve to keep the grain in contact with the apron B, the proper pressure being maintained by a spring, E, the tension of which is adjusted by set-screws e. rEhe wires d are connected to a cross-bar, d', at the top, but the side wires are" also extended beyond and passed through the' cross-beam q, to which the spring E is secured, and also through holes in the spring E until the shoulders cl2 thereon come in contact therewith.

At the bottom the wires are connected to a cross-bar, d3, which is connected,- by a'link, d4, with arms d5, attached to a rock-shaft journaled in upright g2, and having an operatinglever, C17. driver by hand or otherwise. By its operation the wire frame D and also the elevating device are lifted at the bottom from the apron B, or brought near. thereto.

F represents a cut-off with one or more prongs, f. When elevated it allows the grain to pass beneath; when let down it stops the passage of the grain. It is supported in bearings on the upright g2 and g3 on one side of the frame,and operated by an arm, f,in connection with cams.

G represents a traction-wheel, from which motion is given, through bevel-gears g and g and axle g3, to cam-wheels H I. It travels on the ground and supports the grain elevating and binding devices. The shaft g5 revolves in bearings or on cross-beams g8 and gg.

The wheel H has on the outside two cams or projections, h2 and h3, the latter extending beyond the former, and on the inside cams h and h4. extending around about two-thirds of lthe circumference. The cam h4 operates the cut-off F through the arm f. The wheel I has a cam or projection, t', on its outer face.

K represents a pulley on the end of the axle or shaft g2, and from it power is commu- This lever may be controlled by the y IOO nicated, through endless belt le and pulley Kb, to the roller Z), to move the apron B, and through pinions Kc to the roller C2, to move the elevator C.

The axles g2 and g3 have their bearings on the beams q. Upon the same aXle g2 a second pulley is secured inside of the pulley K. 0n this pulley and 011 the pulley K runs an endless belt, 7c.

L represents a belttightener. It is pivoted at Z', and has a roller, Z, to run on the belt la. The belt-tightener is raised by the action of the cam h of cam-wheel H upon the arm Z3, land then the belt k runs loose and the apron A stops, when the arm Z3 presses the roller against the belt, tightening it andY starting the apron A. The tightener L is curved,as shown, to spanthe pulleys on shaft g2.

M represents the binders table, extending upward at the back. Itis slotted at m and m', and also on the edge at fm2.

N represents the gavel-compressor or compressing-arm. It is rotated forward and back through the slots m and m2 in the binders7 table by means of the pinion a on the shaft a, which is journaled in bearings on the frame, and to which the compressor is secured.

O is a wheel having` teeth cut on a portion of its circumference, which gear with the pinion n. It is supported by a short shaft resting in a bearing on one of the uprights, Q7. It is partially rotated back and forth by levers o 0, pivoted at o2 and o3, and connected by links o4 and 05 to arms o6 and 07, rigidly secured to the Wheel 0.

The lever 0 is operated by the cam h2 to throw the compressor N forward to form and compress the gavel, and the cam h3 operates the lever 0 to returnit to its position behind the table.

P represents a wire grain-receiver. It is formed of bent wires, which project through the slots m and m. They are secured at the back 'to a rock-shaft, p', having an arm, p2, at the outer end. This arm is connected by a link, p3, with the lever p4, pivoted at p5, and operated by the cam t' or camwheel I.

The cams on the wheels II and I are relatively arranged so that the wire receiver P is lifted as the compressor N returns.

The drop 'F and the belt-tightenerL are operated simultaneously, or with the drop a little in advance.

In oliieration, the grain, as it falls from the cutters upon the apron A, is carried forward thereby, and is carried upward by the apron B and the prongs or teeth ofthe elevating dedevice G, which project between the wires d and support the grain as it rises. It is then delivered to the binders table M until the compressor N is operated and the gavel formed. The belt-tightener L is lifted as the cam 71, is

Vbrought into contact with the arm Z3, the belt happens before the movement ofthe com pressor begins to allow any grain on the elevator to be delivered. Any grain delivered thereafter is held by the wire receiver P, which is lifted by the action of the cam fi on the wheel I through the connecting mechanism above described, so as to remove the grain from behind the compressing arm and allow it to return to its former position more easily.

The gavel formed may be bound by hand or a suitable self-binder.

As the cam-wheels revolve the belt-tightener is released and the prong j' lifted, and grain is again delivered to the elevator by the apron A.

When the compressing-arm N has returned l to its position behind the table the wire receiver drops to its first position on the table.

By the intermittent motion of the apron A the grain for one sheaf is separated from that which is to yform the next one, and this separation takes place at the angle formed by the aprons A and B, and is rendered more complete by the drop F, as it serves to hold the grain on the apron till the separation is made by the removal of the grain from the angle by the elevator. This separat-ion is effected autom atically. As a considerable bundle collects in the angle, to enable it to be properly lifted bythe elevator the wire frame D is moved outward by the handle dl, so as to give sufcient room between the wires and the apron B. The proper pressure of the wires against the grain is secured by the spring E.

.Instead of using the belt-tightener to start or stop the apron A, this result may be accomplished by shifting the belt from a loose to a fast pulley, or vice versa, or by means of a clutch in connection with a loose pulley, the operation being effected by cams in substantially the same manner as the belt-tightener is operated. The belt-tightener or its equivalent may be operated by the driver.

Instead of using a sin gle-leaf spring, E, spiral springs might be employed, or several springs.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is- Y yl. The combination, with the elevator of a harvester, of an intermittently-moving receiving-apron, as specified.

2. The combination, in a harvester, of the elevator and receiving-apron with a drop having one or more prongs, and adapted to be raised and lowered, substantially as described.

3. The combination, in a harvester, of the receivin g-apron with mechanism, substantially as described, adapted to automatically stop and start said apron, as set forth.

4. The binders table M,extended upwardly at the back and provided with slots m m2, in combination with the compressor N, arranged to operate in connection therewith to form the gavel, substantially as described.

5. In combination with the gavel-formng IOO IIO

mechanism of a harvester, a Wire grain-receiver projecting through the slotted binders table, arranged as described, to lift any grain that may have fallen thereon out of the way of the returning compressor, substantially as set forth.

6. In a harvester, the combination of devices for receiving the cut grain and continuously-operating devices for elevating the same with devices for retaining or holding the grain on the receiver While a separation of the grain to form the different gavels or sheaves is effected by the elevator, substantially as described.

In testimony that I claim the foregoing as 15 my own I affix my signature in presence of two Witnesses.
